April will bring a new product– the Apple Watch into the market. Last week, the watch was firstly introduced by Tim Cook, Apple's CEO. The price of the watch is from $349 to $1,099, depending on its size and whether it is a sports or regular one. Apple engineers and designers have put in a lot of thought and hard work into creating this small screen on your wrist. The sensor(传感器)on the screen not only finds your finger, but also knows the difference between when you are tapping(轻触), and when you are pressing harder.

    The watch also has haptic feedback(触觉反馈). You can send personal messages to your friend —such as drawing a star or a special sign with your fingers, or tapping the watch, say 3 times, and your friend will receive those taps on their wrist.

    Besides telling the time, the watch will use 'Bluetooth' to connect with your iPhone and show calls or text messages that come in.

    According to Tim Cook, the watch may open up a whole new area of applications（应用） that we had never thought of. Some car factories like BMW have developed an app that allows its car owners to open their cars with the watch. A 'Hotels' app may allow you to open the door to your hotel room without worrying about losing the smart-card. And finally, even at the airport—passengers may be able to simply wave their wrist to check into their flight.

    The biggest use of the watch, however, is as your personal fitness coach. The watch can show your pulse (heartbeat) using a sensor at the bottom of the watch. It also has the same sensor as your iPhone, so it knows when you are moving, and also how much you are walking or running. It will remind you if you have been sitting for too long without taking exercise.

    Do you know kind words and light music can help plants grow better? Many people talk and play music to their plants. And many people try very hard to protect their plants from loud noise, strong light and bad smell. That's not all. Some people are very careful about what they say or do in front of plants. They don't talk about unhappy things and won't beat a fly near their plants.

    Do plants have feelings? Many pupils think so. Even a few scientists think that plants have feelings. But most scientists don't agree. They don't think that plants call be happy, worried, angry, loving or afraid. They don't believe that a plant's feeling can be hurt.

    Professor Cleve Backster in America did an experiment and said that plants have feelings like human beings. He published an article in a magazine in 1968. People began to pay more attention to this topic since then.

    As everyone knows, animals are our friends. Of all the animals, dogs are friendly to 1.

    Dogs are always staying 2 human beings. They are in different colours. There are many different 3 of dogs. Hunting dogs can 4people get more prey(猎物). The seeing-eye dogs can help 5people a lot. The police dogs can help the police.

    Today it is 6 to imagine the life without dogs. Maybe everyone is happy to see dog. Dogs are good at7 and smelling. Some dogs can find the people who are trapped(困) 8 the broken house. Some dogs can help take care of the houses. 9someone strange comes close to the house, they will bark to frighten him. Even some dogs can help look after kids when their 10 are not at home.

    In a word, dogs are our best friends among all animals.

On 27th April 2022, NASA astronaut Jessica Watkins made history as she entered space on a SpaceX rocket. Dr Watkins is now the first black woman to serve on a long-term mission (任务) to the International Space Station(ISS).

Jessica is not only an astronaut, but also a geologist(地质学家). She was a member of the planning team for several of NASA's Mars missions. Her knowledge of geology helped decide rovers' paths on Mars.

In 2017, Jessica began a two-year programme to become a NASA astronaut. It helped her to prepare for her work in space. As part of that work, she took part in an underwater training mission. She lived in an underwater lab for nearly two weeks.

Jessica and the three other astronauts will spend six months on the ISS. Their job includes a number of scientific experiments. They will also help take care of the space station.

Before Jessica, only four other black women had gone on short-term missions into space. "I'm building on the foundation(基础) laid by them," said the astronaut. She hopes her work will set a good example for all children, especially black children. "You are well able to go on space missions and to achieve success!"

Most parents agree that children should eat healthy food. But how can they{#blank#}1{#/blank#}(鼓励)their kids to eat healthily? Our research suggests it should begin by getting parents to do the same. 

We often see parents choose healthy food like{#blank#}2{#/blank#}(牛奶）and eggs for their kids. As for themselves, they would prepare something unhealthy. Why? They are not{#blank#}3{#/blank#}（确定）whether their kids would like to eat the healthy food. So, their own dishes can be a{#blank#}4{#/blank#}(第二;另一)choice for their children. If kids eat from their parents' dishes, both of them may have unhealthy diets. 

Luckily, we found a{#blank#}5{#/blank#}简单）way: asking parents to think of their meals as their own, rather than as a choice for their children. 

To do the research, we worked with a school. The school{#blank#}6{#/blank#}(计划）to help children eat more healthily. It provided a free{#blank#}7{#/blank#}(晚餐）for 100 families. We noticed all the parents{#blank#}8{#/blank#}(仔细地)chose a healthy meal for their children. Then be-fore choosing for themselves, we asked{#blank#}9{#/blank#}(一半)of them to think of their meal as "for you and only you!" The others were not asked to do that. 

The{#blank#}10{#/blank#}(结果）?Many more parents from the first group chose healthy food for themselves!
